What is the temporal resolution of the visual system?

Posted by RobertPOShea on 16 Jan 2008 at 16:49 GMT

this limit to rivalry is an order of magnitude larger than temporal resolution of the visual system

The authors need to say what the temporal resolution of the visual system means and what its value is. At the very least they should give the precise order of magnitude by which binocular rivalry's temporal limit is greater. I'm guessing, without reading the cited papers, that it's the "shutter speed" of the visual system, 100 ms, and 3.5 times respectively. Am I right?

We meant to refer to the psychophysically measured critical flicker fusion frequency (~60Hz, though measurements vary somewhat between studies), as well as the physiologically measured flicker fusion frequencies (around 100 Hz for early visual neurons). Both limits are discussed in e.g. van de Grind et al (1973), see main article.
Indeed the ~100 ms limit is an often-reported temporal limit of the visual system (e.g. VanRullen & Koch, 2003, Trends Cogn. Sci.) as well, and also this limit is quite a bit shorter (in milliseconds) than the limit we report.
